Answer:
Step-by-step explanation:
An equation in the vertex form is written as
Where the point (h, k) is the vertex of the equation.
For an equation in the form the x coordinate of the vertex is defined as
In this case we have the equation .
Where
Then the x coordinate of the vertex is:
The y coordinate of the vertex is replacing the value of in the function
Then the vertex is:
Therefore The encuacion excrita in the form of vertice is:
To find the coefficient a we substitute a point that belongs to the function
The point (0, -1) belongs to the function. Thus.
<em>Then the written function in the form of vertice is</em>
10/1 = 10
50/5 = 10
x= hours
y=amount of money earned
y=10x
slope = 10
Answer:
24 minutes
Step-by-step explanation:
This can be explained with the equation y=2x+10 (I chose 2 arbritrary variables, any are acceptable). A week is equivalent to 7 days so x=10. Plug this into the equation and you end up with 24, because 2(7)+10=24
Answer:
Part A - 2a*2b Part B- 2(a*b)
Step-by-step explanation:
Part A)
V=lwh of larger prism - lwh of smaller prism
=9a*a*a-9a*b*b
=11a-9a*2b
=2a*2b
Part B)
2a*2b
=2(a*b)
